Jonathan played Lenny, the middle son of the cantankerous East End patriarch Max, in the RSC's revival of Harold Pinter's play.

When Lenny’s brother Teddy returns from America, where he works as an academic, with his new wife Ruth in tow, the family unit restructures to accommodate a new matriarchal figure. Ruth’s maternal role, however, stretches beyond the norms as she becomes the living embodiment of the old saying about maids in living rooms, cooks in kitchens and whores in bedrooms.
